A light wave is reflected from a mirror. The incident and reflected waves superimpose to form stationary waves. But no nodes and antinodes are seen. Why?

At nodes in stationary waves

A wave is reflected from a rigid support. The change in phase on reflection will be

In stationary waves, antinodes are the points where there is

In a stationary wave, at the antinods there is a change in

The pressure node in a stationary waves is a

The pressure antinode in a stationary waves is a

At nodes, the velocity of stationary wave is

In a longitudinal stationary waves, node is a point of

The reflected waves from on ionsphere are ………..

A wave of length 2m is superimposed on its reflected wave to form a stationary wave. A node is located at x=3m , the next node will be located at x equals to
